Abstract

Ensemble filtre (1) comprenant un boîtier allongé (2) contenant de nombreuses longueurs de faisceaux de filtres discrets (3) mises bout à bout en série. Chaque longueur de faisceaux de filtres (3) est constituée d'une multitude de fibres polymères creuses microporeuses d'un type selon lequel le produit à filtrer est introduit à l'extérieur du paquet de fibres, le perméat étant extrait à partir d'une ou des deux extrémités de décharge du perméat (4) des lumens de fibres. Le système comprend également un ou plusieurs passages d'alimentation de forme allongée (6 et 7) ainsi qu'un ou plusieurs passages de forme allongée de retour du perméat, chacun de ces passages de retour du perméat étant en communication fluidique par flux avec chacune des extrémités de décharge du perméat (4) des lumens de fibres, si possible via les passages intermédiaires (9).
